It's all a matter of personal choice and the intended use of the vehicle. If I'm going to build a car that has to perform well at the drag strip or on a road course and hold the supension geometry close to the design figures, then I might use harder material to facilitate that.
But on the street, I will not tolerate the harshness of materials other than rubber. The same way I will not tolerate a shift kit in an automatic transmission on the street. Having my head jerked back on every shift is not my idea of driving pleasure. I'll tolerate it at the drags because that, in my opinion, is what a shift kit was designed for in the first place and I only have to tolerate it for 2 shifts on a 3-speed box.
Here's another for instance on the OEM bushings, these are for a Chevelle upper link at the rear. Go to the boneyard and buy an upper link. Beat the bushing out of it and closely measure the i.d. at both diameters (there's a step in there). Machine a bushing tube to replicate the measurements of the OEM piece. Weld the bushing to your link rod. Buy these Moog bushings at your parts house. Press in new Moog bushings. Fabricate mounts to accept Moog bushing bolt. Enjoy.

Bottom line: If you are able to tolerate some harshness in the ride quality and it is important to you to hold the design dimensions close, then use the Delrin bushings you have. If you're inclined toward a smoother, quieter, more compliant ride quality and holding the design dimensions close is not that important to you, then fabricate some bushing tubes and use the Moog rubber units.Last edited by techinspector1; 10-23-2008 at 01:03 PM.
